POWER-TRANSMITTING MECHANISM.

Specification of Letters Patent.

Patented Dec. 16,1913.

Application filed September 12, 1912. Serial No. 720,037.

To all whom it may concern.

Be it known that I, ANTHONY J. Sermonnnn, a citizen of the United States, residing at Donaldsonville, in the parish of Ascension and State of Louisiana, have invented certain new and useful Improvements in Power-Transmitting Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved power-transmitting mechanism, and it consists in the constructions, combinations and arrangements herein described and claimed.

An object of my invention is to provide an improved power-transmitting mechanism, by which the rocking motion of a curved member will transmit a complete double oscillation to a pivotally-supported device, such as a fan, during each forward and rearward rocking movement of said curved member.

A further object of my invention is to provide a simple and eflicient fan device adapted to be readily attached to rocking chairs for causing a complete double oscillation of the fan during each forward and each rearward rocking movement of the chair.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views :-Figure 1 is a side elevation, showing a rocking chair in its normal position at rest, with one embodiment of my invention applied thereto; Fig. 2 is a similar view showing the positions of the parts when the chair has rocked to substantially one-half of its forward movement; and Fig. 3 is a rear elevation, showing the chair rockers and my improved device clamped thereto, the parts being in the positions shown in Fig. 2.

Referring to the drawings, 1 indicates the curved rockers of a chair, which are shown normally supported at rest on a floor 2 at an intermediate portion 3 of their arcs.

A frame 4: is rigidly supported on a cross bar 5 clamped at 6 to the rear ends of the rockers 1; the upper end of said frame being shown clamped to the chair back by straps 7, and provided with forwardly-inclined members 8 connected by a cross piece 9. A support 10 for the attachment of a suitable fan 11 is pivoted at 12 to the cross piece 9, and adjustably connected by a link 13 to a bell-crank lever 14 pivoted at 15 on the top of said frame 41.

A lever 16 is fulcrumed at 17 on a cross bar 18, which latter is clamped at 19 to the curved rockers 1 at points adjacent to the normallysupporting intermediate portions 3 of the latter; said lever being adjustably connected by a link 20 to one arm of the bell-crank lever 14-, and the rear portion of said lever sliding between guides 5 on the cross bar A spring 21 is attached to the frame 4 and adjustably connected to said lever 16 for yielclingly maintaining a roller 22 on the forward free end of said lever in contact with the floor at a point substantially midway of the forward are of swing of the curved rockers 1 from the position of rest of the latter, as shown clearly in Fig. 1 of the drawings.

In the operation of my invention, the forward end of the lever 16 will be swung upwardly about its fulcrum during substantially the first half of the forward rocking movement of the curved rockers 1, thereby swinging the fan 11 through its forward stroke from the position shown in Fig. 1. lVhen the rockers 1 have thus rocked through substantially one-half of their forward arc, the parts are in approximately the position shown in full lines in Fig. 2, and a completion of the forward rocking movement of the rockers 1 acts to raise the lever roller 22 to permit the spring 21 to return the fan through its rearward motion to the position illustrated in Fig. 1. During the return rearward rocking of the curved rockers 1, the above steps will be repeated, and the fan 11 will thus be swung through a complete double oscillation during each forward and each rearward rocking movement of the chair.

The range and extent of the swing of the fan 11 can be readily varied by means of the adjustable connections of the links 13 and 20, thereby enabling the device to be conveniently adjusted to meet all practical conditions.

I have illustrated and described preferred and satisfactory constructions, but changes could be made within the spirit and scope of my invention.

I claim In a fan attachment for rocking chairs, the combination of a cross bar adapted to be clamped to the rear ends of the chair rockers, parallel guides extending upwardly from said cross bar, an upright frame.

rigidly mounted on said cross bar, a forwardly-inclined rectangular frame rigidly secured to the upper end of said upright frame, a bell-crank lever 'fulcrumed on said upright frame, a fan pivotally mounted on the forward end of said inclined frame in position for swinging rearwardly through the latter, a link adjustably connecting said bell-crank lever and fan, a cross bar adapted to be clamped to the medial portions of the chair rockers, an actuating lever pivotally mounted on said last crossbar with its apsnses rear end slidably engaging said upwardlyextending guides, a link adju'stably connecting said actuating lever to said bell-crank lever a spring secured to said upright frame, and means for adjustably attaching said spring to said actuating lever for maintainingthe forward end of the latter in engagement with the floor.

In testimony whereof, "I affix im y signature, in presence of two witnesses.
